Simon Cowell is keen to have another baby and is hoping for a girl this time, according to his X factor aide Sinitta.

The former pop star, who has long been friends with Cowell, made the claims in an interview with Closer magazine earlier this week.

'Everyone assumed he'd be this harsh parent, but he's so gentle with Eric.'
